Leonard: It's just Penny hit me with some pretty big news and it's a lot to process.
Sheldon: And you'd like to do that quietly. I respect that.
Leonard: She said she doesn't want to have kids.
Sheldon: Maybe she didn't mean it, like when you said you didn't want to talk about this.
Leonard: Forget it.
Sheldon: Do you want to have children?
Leonard: Well, I always assumed we would and now I find out, you know, I might be the last of the Hofstadter line.
Sheldon: Doesn't your brother have children? And your sister. She kept the Hofstadter name and has five healthy boys: Neil, Jeffrey, Scott, William and baby Richard.
Leonard: I'm going back to being quiet.
Sheldon: Sweet.
